weirdly mine shakes and vibrates for maybe 10-20 seconds when I start it up then smooths out. I think of it just some hiccups for a high performance engine. my motorcycle engine does the same.
that is true, because even with new coils, good plugs, New o-Disa ring gasket w high temp gasket sealer and very good clean ICV,DISA, and new vaccum lines and i still get that hesitation just right when its coming down from warming up on 900-1k rpm (higher bad Vanos i suppose) to 700 rpm. (Normal idle)

Ive replaced Vanos, VCG, spark plugs, air filter, OFHG, cleaned MAF, nothing changed. the hiccup does not make the engine run rough or anything. engine tone does not change. I think could be engine mounts.
